The arc resulting from the tripping of a circuit breaker is prevented from damaging the contacts. How is this done?

Correct Answer: Option A — directing the arc into an arc chute

Arc chutes use metal splitter plates to divide, cool, and extinguish electrical arcs generated during circuit breaker tripping. This IEEE 45 and 46 CFR Subchapter J requirement protects contact surfaces from rapid degradation and erosion.
